    Welcome to the forum.
    Sound's like your carby's might need a clean out, possible high float level too?

    Please use the following link to identify the various bits on your bike. Engine number and frame number can be used to determine what year/model they are. Bodywork, frame, carbs and others can also be identified to specific years/models

    Models... from 1986-1988 you have the 2KR which is skinny steel frame without EXUP. In 1989 you have the 3HX series which is a 2KR with EXUP valve and servo motor. Also in 1989 is the 3LN1 which is the thick aluminium frame and lots of changes to the series, including EXUP valve and servo motor. From 1990-1992 is the 3LN3 and 3LN5. Both are the same except for colours of the tank/fairings. In 1993 you have the 3LN6 and 3LN7 which are restricted to 40 horsepower and have a lower maximum RPM due to different camshafts and CDI boxes.

    sounds like the worn needle jet and jet needles we've all enjoyed experiencing so much

    where are the thread librarians this evening, they can usually bring all of the relevant threads before I even have time to make a post?
